Tesla has confirmed its V4 Superchargers will be capable of 350kW. Currently, V4 Superchargers are limited to 250kW, the same as its V3 counterparts.

Tesla confirmed this information in a planning submission for a charging site in Swindon, UK. The submission also contained images of the charging stalls, which confirmed a payment screen and an oval base. The submission also states, “All charging units are universal and can be used by an EV user.” EV owners that want to use Tesla’s “ultra-rapid” V4 Superchargers will be able to take advantage of them, despite not having the Tesla app or account.

Maximum Charging Speeds For V4

V4 Superchargers are currently limited to 250kW, but with the increase to 350kW, we'll see much higher burst speeds. Charging at 350kW could allow Teslas to charge at up to 1,400 miles per hour, or 115 miles in just five minutes. While these are tremendous speeds, your vehicle will not charge the entire time at these high speeds.

To achieve the full 350kW speed, your battery will need to be pre-conditioned and at a low state of charge. For Teslas, this is between about 5 to 30 percent. If those criteria are met, your vehicle will ramp up to its maximum charging speed for a short period of time.

As your vehicle gets closer to finish charging, the speeds will slow down to preserve battery health and longevity.

Faster Future Charging

Tesla doesn't plan to stop at 350kW. At the Tesla Semi unveiling event, CEO Elon Musk and Dan Priestley, Tesla Semi program manager, confirmed that the Cybertruck will use the same charging technology as the Tesla Semi, allowing it to accept 1MW of DC fast-charging. This will apparently be possible because of Tesla’s innovative “immersion cooling technology.”

V4 Superchargers Make Appearance at Goodwood Festival

A few weeks ago, the V4 Superchargers were on full display at the Goodwood Festival of Speed in the UK. The Tesla Owners UK Twitter account shared close-up images of the new Superchargers, which interestingly had space for a screen and contactless payment terminal.

Tesla allows owners to seamlessly pay for their charging sessions. Their car is linked to their Tesla account and credit card, which is charged upon the completion of a session. When Tesla started opening Superchargers to non-Teslas, these owners needed a way to pay for their EV juice. They added the “Charge Your Non-Tesla,” which guides non-Tesla owners to create a Tesla account and add their payment information.

However, the addition of the contactless payment device in V4 removes the need for an app entirely. Non-Tesla owners may be able to simply pull up to a Supercharger, swipe their card, and charge.

First V4 Supercharger Opens

Tesla opened its first V4 Supercharger in Harderwijk, Netherlands earlier this year. The site has 16 stalls and includes longer charging cables to make it easier for non-Teslas to charge. The first V4 site was originally going to be in Danvers, Massachusetts.

European regulations state that an app shouldn’t be required to use an EV charging station, which is likely why V4 stations will have the contactless payment terminal.

Tesla Accelerates India Entry: Eyes Gigafactory India

Tesla’s much-anticipated official entry into the Indian market appears to be shifting to a higher gear, with recent reports from Business Standard (paywall) indicating that Tesla is now looking into establishing Gigafactory India. Business Standard points to Tesla exploring land options in Satara, Maharashtra.

Satara is about 250km (155 mi) from the Port of Mumbai, placing it in an excellent location to easily receive parts and materials from other countries, as well as ship completed vehicles elsewhere around the world. The potential facility is reportedly planned as a “Completely Knocked Down” or CKD assembly plant, which means that Tesla would import parts and then assemble them locally. 

This is key to Tesla’s strategy in addressing India’s traditionally high import tariffs on fully built vehicles, which have been a major hurdle for Tesla in the past. This push aligns with India’s updated EV policy, which calls for reduced import duties on EVs priced at $35,000 USD or above for companies that commit to investing at least $500m USD in local manufacturing facilities between 2024 and 2027. 

According to the report, Tesla is prepared to invest substantially more, with figures around $2-3 billion USD cited for a plant capable of doing final assembly on up to 500,000 vehicles. Tesla supposedly aims to roll out the first locally assembled vehicle from the facility no later than March 2026.

Building the Indian Foundation

Beyond just manufacturing plans, Tesla has been actively laying the groundwork for its future Indian operations. Tesla has reportedly finalized leases for its first showrooms in Mumbai and Delhi - two of the largest cities in India. An office space in Mumbai to headquarter Indian operations is also on that leasing list.

Tesla has also begun to hire its initial tranche of employees, with over 30 positions already posted. Tesla is also hiring Autopilot Vehicle Operators in several locations, indicating that Tesla intends to test at least the FSD suite in one of the most complex traffic situations around the world. 

Elon Musk also confirmed that he plans to visit India and speak to the Indian Prime Minister, likely to broker a deal focusing on building out Tesla’s presence and bringing new technology to the country.

The road to India has not been without its complexities. Reports confirmed the resignation of Prashanth Menon, Tesla's India head, with oversight of Indian operations temporarily shifting to Tesla's China team. Furthermore, earlier discussions with potential joint venture partners, such as Hyderabad-based Megha Engineering for land acquisition, reportedly did not materialize, leading Tesla to explore other avenues and locations like Satara.

Despite all the setbacks, Tesla’s efforts indicate that they are more determined than ever to make a formal and official entry into the Indian market.

Tesla's Spring Update Tear Down: New Grok Code, Ridesharing Features and More

By Karan Singh

Tesla’s software updates often contain far more than the release notes show, whether they’re undocumented features or preparation for the next big thing. The 2025 Spring Update is no exception - it’s filled with undocumented changes and, of course, new, inaccessible code that points to upcoming features.

Tesla hacker greentheonly on X has been digging into update 2025.14 and found some intriguing additions and hints about what’s coming next, so let’s take a look.

Grok Incoming

New hidden UI elements have been found pointing towards the integration of a Grok-powered smart assistant for Teslas. This includes references to a “personality” button, just like the Grok app. Tesla is likely hard at work on an advanced conversational AI and integrating the ability to control your vehicle

Grok is the smart assistant that’s expected to replace the ancient voice commands that are available today. However, expect anything beyond vehicle commands to require Tesla’s Premium Connectivity.

While none of these new elements are active just yet, it is a good indication that it is likely on its way quite soon.

Siren Detection UI Removed

Code related to user-facing elements for siren detection has now been removed. We’ve confirmed that the orange dot is still in place with the Spring Update, but elements related to future changes and a UI for siren detection have since been removed from the code base.

Removals don’t indicate much - Tesla could be refactoring the code while they’re working on this or have changed directions on how to implement a future.

Insights into the New Dashcam Viewer

More significantly, for users on HW3, Green reported that the newly improved Dashcam Viewer isn’t just an improved version of the video viewer, but it was built from the ground up, and it’s now web-based. This technical detail explains why the updated viewer is only rolling out to AMD Ryzen vehicles and not older, Intel-based vehicles. HTML-based apps are often quicker to develop but usually require more resources to perform smoothly, which may be why we’re seeing the Ryzen infotainment system requirement.

This likely means that the new Dashcam Viewer won’t arrive on Intel vehicles in a future update unless Tesla can optimize the viewer enough to perform adequately on the older hardware.

HW3 vehicles already missed out on the new B-pillar recording feature. While Green thinks it’s technically possible to bring this feature to HW3 cars, unknown technical issues are likely preventing it. Older HW3 vehicles without a USB port in the glovebox only include USB 2 ports, limiting bandwidth, which could be one of the reasons, among others.

New Key Types

Perhaps a hint at Tesla’s third-party Robotaxi fleet ambitions, Tesla is building out new types of keys.

Rider Keys: These new keys appear to be designed to allow designated riders to access vehicles that are operating in “fleet mode.” This functionality sounds very much like what will be needed to allow Robotaxi customers to access a vehicle temporarily while they’re being given a ride.

Pre-Delivery Keys: Another new key type found is “pre-delivery.” While we don’t have an exact purpose nailed down quite yet, we’re assuming this could potentially allow new owners limited access to their vehicles for inspection prior to officially accepting delivery.

That’s plenty of interesting stuff found in the 2025 Spring Update - and we’re excited to see even more in just a few short weeks once Tesla launches their Robotaxi network in Austin.
